` will enable others skilled in the'art to which it appertains to make and use the same.

My invention relates to improvements in freight-car locks and seals, especially those designed for railway-cars, and has for its object a lock with a seal which, while composed of few parts, can be manufactured at a comparatively slight expense, is durable in character, and efficient in operation; and for this purpose it consists of the combination and arrangement of parts hereinafter set forth.

In the accompanying drawings, which form a part of this specification, Figure l represents a front View of a car seal-lock embodying my invention. Fig. 2 represents a central vertical section on line a: ce, Fig. 1. Fig. 3 represents a face view of the rear portion of the frame with inclosed spri-ng. Fig. 4 represents a perspective View of the locking-bar with cross-bar and loop thereon. Fig. 5 represents a face View of the plate or seal detached from the frame, and Fig. 6 represents a sectional view of the bolt andadjacent parts.

Similar characters designate like parts in the several figures.

A designates the frame of the device, composed of two main parts B and C, respectively. The front part or portion B of the frame has secured to its face, on the sides thereof, the pieces D D, the inner walls of which having overhanging edges, forming the Ways E E for the locking seal or plate F. One end of the recess or passage E between the said pieces D D is open for the admission of the said seal F, while the other end is closed by a crosspiece G, likewise secured to the front face of the portion B of the frame. The rear surface of the said portion Bis provided with the two parallel beads or ribs H H, which contact with the inner face of the side walls of the portion C, so as to prevent any lateral movejment of the said parts B and C When joined together by bolts J, which pass through open- -front portion B of the frame and be flush with the face of said seal when the latter is locked in place. Within said rear portion C is a spring-plate P, adapted to bear against the cross-bar N, and thereby force said staple into said slotfof the seal. The said spring is held in place bya keeperp', secured to the part C, which engages in an opening in one end of the said spring. A spring-bolt Q, secured in the portion B of the frame, is normally adapted to enter the slot or groove f in the plate F, so as to engage the loop or staple O when therein, holding it from displacement, and thereby preventing any movement of the locking-bar M. The upper end of the seal F is slotted or grooved atf to permit the movement of the projection q on the bolt. The inner portion of the frame C is provided with cross-pieces or'walls R R, between which and the side walls of said frame the cross-bar N is normally held at right angles to the locking-bar M.

When the plate or seal F is secured in place in the lock, the slot f' is lled with cement or glass, so that any tampering with the lock is readily known. By having the one end of the passage E open the broken pieces of the seal when destroyed readily escape therefrom without necessitating the trouble of removal by hand..

The manner of operation of the device will be readily apparent from the description already given. The frame A is secured to the casing of a car to the left of the door, and when a hasp on the door is placed over astaple on the casing below the lock the lower end of the locking-bar M is passed throughI IOO place, and the fact of the locking of the car is readily apparent by the appearance of the loop or staple ush with the face of the seal F. Having thus described my invention, What I desire to secure by Letters Patent isl. In a device of the character described, a frame with a face receptacle therein, a lock- 4 ing-bar, a cross-bar provided with a loop engaging said bar, a plate or seal fitting in said face receptacle and provided with an opening to receive said loop and a spring-bolt adapted to engage said loop said parts being combined substantially as described.

2. In a device of the character described, a frame With a face receptacle therein, a locking-bar in said frame, a cross-bar provided with a loop engaging said lockingbar, a spring bearing against said cross-bar, a seal fitting in said face receptacle and provided with a slot adapted to receive said loop and a bolt engaging said loop.

3. In a device of the character described a sectional frame consisting of front and rear portions, guideways forming a receptacle on said front portion, a locking-bar extending through said frame, a cross-bar pro vided with a loop in said frame engaging said lockingbar, a spring in said rear portion bearing against said cross-bar, a seal having an opening to receive said loop and having its face Hush therewith when locked to said frame, and locking means for said loop, said parts being combined, substantially as described.

4. In a device of the character described, a frame with a face receptacle, a slotted seal fitting in said receptacle, a springpressed loop adapted to enter said slotted seal, a locking-bar engaged by a cross-bar connected with said loop, and means for locking said loop in fixed position.

5. In a device of the character described, a frame With a face receptacle, a locking-barin said frame, a spring-pressed loop held in said frame, a seal fitting in said face receptacle with a groove therein adapted to receive said loop said loop having means connected therewith for engaging said bar locking the same, and a locking-bolt for said loop, said parts being combined substantially as described.

6. In a device of the character described a frame, a locking-bar with a groove therein, a cross-bar adapted to enter said groove and hold said locking-bar in fixed position, a loop on said cross-bar embracing said'locking-bar, a spring in said frame bearing against said cross-bar, a seal having a groove therein to receive said loop and a spring-bolt in said frame adapted to engage said loop, said parts boing combined substantially as described.

7. In a device of the character described, a frame having a face receptacle, a seal fitting in said receptacle and provided with a transverse slot and a groove, alocking-bar, a springpressed cross-bar engaging said locking-bar and provided with a loop entering said slot, and a spring-bolt engaging said loop and provided with a projection guided in the said groove, said parts being combined substantially as described.

In testimony whereof I aiix my signature in presence of two Witnesses.
